Joshua Báez (born June 28, 2003) is a Dominican-American outfielder for the St. Louis Cardinals who made MLB history on August 15, 2026, by hitting a home run in each of his first three major league plate appearances during his debut against the Chicago Cubs at Wrigley Field—all off pitcher Matthew Boyd, making him the first player ever to accomplish this feat. Raised in Boston after early childhood in Santo Domingo, Báez learned English with Google Translate and starred at Dexter Southfield School, earning the 2020 Massachusetts Gatorade Player of the Year award despite the pandemic-canceled season. Drafted in the second round (54th overall) of the 2021 MLB draft for a $2.25 million signing bonus, he climbed through the Cardinals' minor league system over several seasons. His 2026 breakout at Triple-A Memphis—where he hit 34 home runs and set a single-game franchise record with four on June 16—prompted his call-up just one day before his unforgettable debut. With his explosive start, Báez turned a long developmental path into an immediate, record-smashing arrival on the big-league stage.
